THE EFFECT OF SUCKLING TRAITS ON GROWTH RATE OF CALVES IN GIR CATTLE
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 60
Abstract
The present study was conducted to study the effect of suckling traits on growth rate of calves in Gir cattle. Growth rate due to duration from placing the calf nearby cow to holding of teat by the calf, number of attempts to teat seeking, number of strokes made during suckling for letting down and let down time. A total of 13 observations of growth rate, each at 15, 30 and 45 days from four different Gir cattle farm were recorded in calves due effect of various suckling traits in Gir cattle. Average growth rate (Kg) at 15, 30 and 45 days due to effect of duration from placing the calf nearby cow to holding of teat by the calf was significantly (P<0.05) higher at 45 days than at 15 and 30 days. Effect of number of attempts to teat seeking on growth rate was significantly (P<0.05) higher at 15 days than at 30 and 45 days. The average growth rate due to number of strokes made during suckling for letting down was significantly (P<0.05) higher at 15 days as compared to 30 and 45 days. The mean growth rate due to let down time was significantly (P<0.05) higher at 15 days than at 30 and 45 days. Highest growth rate was due to number of strokes made during suckling for letting down and lowest growth rate was due to effect of duration from placing the calf nearby cow to holding of teat by the calf, at 15, 30 and 45 days. No significant correlations were observed among duration from placing the calf nearby cow to holding of teat by the calf, number of attempts to teat seeking, number of strokes made during suckling for letting down and let down time, at 15 and 30 days. However, a significant positive correlation (P<0.05; r = 0.65) was recorded between effect of duration from placing the calf nearby cow to holding of teat by the calf and number of strokes made during suckling for letting down at 45 days. It is concluded that suckling traits affect the growth rate of calves in Gir cattle at various days of age. Number of strokes made during suckling for letting down lead to highest growth rate in calves.
